SAFETY RAZOR.

Application 1611 July 17, 1928. Serial No. 123,037.

This invention relates to razors and has special reference to the typeof razor known as a safety razor.

More particularly the invention relates to a safety razor for shavingconcave surfaces such as the armpit or the like. In the shaving of suchsurfaces vious that the user of the razor has to use first one hand andthen the other. Consequently a fixed position for the razor handle foruse by either hand must be a compromise between the two or morepositions most efiicient for shaving with each hand.

One object of the invention is the pro- 5 vision of a safety razorwherein the handle may be readily shifted between positions best adaptedfor use by one hand to similar osisions best adapted for use by theother an Also the angular setting of the blade in such a razor for themost convenient position of use varies with the physical configurationof the user.

A second object of the invention is to provide an improved constructionof razor wherein this angular relation between the handle and blade maybe varied at the will of the user.

With the above and other objects in view as will be hereinafterapparent, the invention consists in general of certain novel details ofconstruction and combinations of parts hereinafter fully described,illustrated in the accompanying drawings and specifically claimed.

In the accompanying drawings like characters of reference indicate likeparts in the several views, and:

Figure 1 is a side elevation of a razor constructed in accordance withthis invention.

Figure 2 is a front view thereof.

Figure 3 is a detail section through the head of the razor on the line3-3 of Figure 2.

Figure 5 is a plan view of the razor blade removed from the head.

Figure 6 is a top plan of the handle portion of the razor.

Figure 7 is an enlarged perspectlve view of the clamping end of saidhandle.

In the embodiment of the invention herein shown there is provided aguard member 10 longitudinally bowed and having an arcuate front edgeprovided with guard teeth 11 curved on their undersides. The rear edgeof this member 10 is also arcuate in form and is provided adjacent eachrear corner with upwardly curved lugs 12. In addition this base memberhas a central open ing 13 surrounded by a serrated ring 14 on it is ob-sthe concave face, the serrations being preferably in the form of bevelgear teeth.

The clamping member 15 is likewise longitudinally bowed and has asub-acute arcuate front edge 16. From the center of the clamp 15projects a screw threaded post 16 and at the rear corners the clamp isprovided with upstanding ears 17 which engage the lugs 12 upon thedevice being assembled, the post passing through the opening 13. Theblade 18 is formed in the usual manner of highly tempered thin sheetsteel and has an arcuate. forward cutting edge 19 and a central opening20 to receive the post 16. Experience has shown that bowing the bladebetween the clamp and guard plates is prone to crack and break suchblade and in order to prevent this I preferably slot the blade from theopening 20 to the rear edge as shown at 21 in Figure 5. The rear edge ofthis blade is preferably straight and at the corners, upon the razorbeing assembled, fits snugly against the ears 17 so that it is held inptroper shaving position.

e handle of this razor includes a cylindrical grip portion 22 from theforward end of which extends an arm 23 carrying a yoke having a back 24and side arms 25 which diverge from the back and have their forward endsconnected by an arcuate rack 26 provided with teeth on its convex sidewhich engage the teeth 14. when the device is assembled. In this rack isformed a longitudinal slot 27 for the reception of the post 16 and theback 24: is provided with a central opening 28 wherein is swiveled asleeve nut 29 having a knurled head 30 by means of which it may bemanipulated. The openin 28 is of such size that the nut is held looselytherein so that the yoke may not only be revolved with respect to thenut but may also be tilted so that the handle 22 may be caused to assumedesired angular relation with the axis of the post 16 and to have itsaxis lie in any desired plane passing radially through the axis of thepost.

The head 30 of the nut 29 is provided with a rounded shoulder 31 whichpasses through the back 24 of the yoke. Consequently, when the nut isloosened upon the post 16 the ham dle and the yoke may be rocked orswung upon the shoulder 31 of the head of the nut. Also the yoke handlemay be turned with relation to the axis of the nut and the stud.Consequently, the handle may be disposed at any desired position withrelation to the axis of the stud and when the nut is tightened upon thestud, the teeth 26 engage in the spaces between the teeth 14 and thebandle is fixed with relation to the guard 10.

It will also be noted that the clamping plate 15 at its rear edge isslightly offset to provide on an inner face thereof a shoulder 15, shownmore clearly in Figure 3 of the drawing, and when the nut 29 is turnedhome on the post 16, the guard plate will cause the blade 18 to conformto the contour of the clamp plate and guard late and the inner edge ofthe blade will be orced in contact with the shoulder 15'. This shoulder15' projects beyond the horizontal plane of the inner face of the clampplate 15 and it will thus be seen that by ad usting the nut 29,adjustments may be made of the plates with respect to one another andcorrespondingly, an adjustment of the blade 18, but in all suchadjustments between the shaving range said blade 18 will conform to thecontour of the clamp plate and remain in contact with the latter.

In using the invention the blade is placed on the clamping plate withthe post 16 projecting through the opening in the blade and the backedge of the blade resting against the ears. Then the lugs 12 areinserted through the ears and the guard plate folded down on the blade.Next the nut is screwed on the post and the handle tilted to the desiredangle and revolved about the post to the desired position after whichthe nut is screwed home. This bows the blade and also locks the handlein the adjustment which is found best adapted for the user's purpose.Naturally the handle may be shifted in position as may be foundexpedient in the shaving operation.

There has thus been and efficient device of the for the purposespecified.

It is obvious that minor changes may be made in the form andconstruction of the invention without departing from the material spiritthereof. It is not, therefore, desired to confine the invention to theexact form herein shown and described, but it is desired to include allsuch as properly come within the scope claimed.

Havin thus described the invention, what isclaime as new, is:
